If you shoot 35 equivalent or above I would go with the Nex7. The EVF and TriNav make sense.

What people are strangely failing to mention here is the failure of the Nex7's sensor with wideangle lenses. This has clearly been established. The sensor is defective. The engineers dropped the ball. All those shooters out there with wideangle Leitz lenses and adapters in hand are not gonna be happy with magenta corners in their images.
Perhaps the Nex8 will have fixed this.
